How do Waterjets work?





Take ordinary tap water and pressurise it to 55,000 psi (3792 bar) and force it through a very small hole. Mix the water with garnet abrasive and you have a very thin stream of water travelling very fast that will rapidly erode most materials.


Some waterjets are “pure waterjets” and don’t add the garnet abrasive. These are used to cut softer materials, such as food, rubber, and foam.



Adding Abrasive into the high-pressure stream of water increases cutting power, the water stream turns into high-speed liquid sandpaper that will now cut all kinds of hard materials like, stone, glass, metal and composites. This is where the term Abrasive Waterjet cutting comes from.



PC-Based Controller





The advanced Omax software simplifies the process of cutting accurate parts across different materials and thicknesses using the inbuilt material database.



Articulated Cutting Head





As an add-on option to OMAX waterjets, this computer-controlled TILT-A-JET cutting head can be used to automatically minimize taper for precise vertical cuts and also tilt forward for faster cutting.



Abrasive Hopper





The abrasive hopper and associated abrasive flow control system provide a metered flow of granular abrasive to the nozzle.



Catcher Tank





The water-filled catcher tank dissipates the energy of the abrasive jet after it has cut through the material being machined.



High Pressure Pump





The pump generates 55000psi of pressurised water for the cutting process.



X-Y Traverse System





A precision X-Y motion system is used to accurately move the nozzle to create the desired cutting path.



Abrasive WaterJet Nozzle





Inside the nozzle, the pressurised water passes through a small-diameter orifice and forms a coherent jet of water. The jet then passes through a venturi section where a metered amount of granular abrasive is drawn into the water stream.


The mixture of water and abrasive particles passes through a special ceramic mixing tube and the resulting abrasive/water slurry exits the nozzle as a cutting stream of abrasive particles travelling at very high speed.
